Phase-dependent heat transport in topological superconductors — •Alexander G. Bauer and Björn Sothmann — Theoretische Physik, Universität Duisburg-Essen and CENIDE, D-47048 Duisburg, Germany

Recently, phase-coherent heat transport in superconducting tunnel junctions has received great interest. On the one hand, it allows for the realization of caloritronic circuits [1]. On the other hand, this can serve as a probe of fundamental properties of quantum matter [2]. Here, we investigate heat transport in junctions made from topological superconductors. We demonstrate that the thermal conductance can probe Majorana physics and enables us to distinguish between helical and chiral superconducting pairing.
